J. COGITO ET Filed May 25. 1927 2 Sheets-Sheet 2 Patented May 13, 1930 UNITED STATES JOSEPH COGI'IO AND BIAGIO INGRASSIA, OF CLEVELAND, OHIO SHIP-LAP JOINT Application filed May 25, 1927. Serial No. 194,136.
This invention relates to a very specific construction of a section of a pipe, and its primary object is to so construct the section that its under and upper sides lie in straight lines throughout its length, whereby when a plurality of sections are united the upper and lower surfaces are in straight lines, whereby the sections are adapted to be supported on a straight foundation and whereby its upper surface is also straight.
Another object of the invention is to have each section constructed alike and each section having its top portion provided with a female portion extending half way around it and the opposite lower end with a shoulder or flange extending half way around it the said shoulder or flange tapered whereby the sections are adapted to receive mortar between them and the said sections readily dropped vertically into position.
In the drawings Figure 1 is a side view of a pipe built in accordance with the invention, a portion of the pipe being shown in longitudinal vertical section.
Fig. 2 is an end view of one section of pipe.
Fig. 3 is an end view of the opposite end of a section of pipe.
Fig. 4: is a perspective View of a pipe section made in accordance with the invention.
Fig. 5 is a perspective view showing a modifled form of the invention.
Referring to the drawings, A. represents a pipe section or pipe length. The particular pipe shown in the drawings is intended to illustrate a poured concrete pipe, but it will be understood that the invention is not limited to a pipe of this character.
Pipes having the improved invention, hereinafter described, can be made of any size or any length to meet the necessary requirements.
Referring again to the drawings, it will be seen that the pipe section or length A is made of one piece and that although its interior is of a circular form its exterior is provided with a flattened or thickened base portion 10,
' the outer edges of which taper or flare outwardly and upwardly as at 11, to meet the outer surface or face 12 of the pipe.
The opposite ends of the pipe are provided with semi-circular shaped outwardly extending female portions 13 and 14:. It will be seen that the female portion 13 extends throughout the perimeter of the upper half of the pipe, while the female portion let extends through the perimeter or are of the low er half of the pipe. The opposite ends of the pipe are additionally provided with the sime-circula-r shaped shoulders or flanges 15 and 16. These shoulders are inset in the pipe, which consequently provides a wall or abutment 17 at the inner ends of the shoulders. These shoulders are staggered in a similar manner to the female portions 13, 14;. That is to say, the female portion at one end of the pipe is at the lower side of the pipe, while the female portion at the opposite end is at the upper side of the pipe.
It will be seen that thefemale portions extend well beyond the end of the pipe and that their longitudinal edges are provided with L- shaped grooves 18, and that due to the fact that the shoulders are inset, an abutment 19 is provided at the inner ends of the grooves 18' where these grooves meet the shoulders.
lVhen the concrete pipe is used in the construction of sewers, it is necessary to protect the pipe against the acid contained in the sewerage water. tions are accordingly made with a depressed or cut out portion which extends throughout the lower half of the pipes. In this cut out portion are placed a series of vitrified line plates 20, which are secured in place by mortar 21, or some other suitable fastening medium. \Vhen the plates 20 are in place, their outer faces are flush with the inner surface-22 of the upper half of the pipe.
By reference to Figure 1, the manner of joining the pipe sections together will be clearly apparent. It will .be seen that the female portion 13 of one sect-ion overlies the shoulder or flange 16 of the adjacent section of pipe at the upper half of the pipe line, while the female portion 14 of one section of pipe overlies the shoulder or flange 15 of the adjacent section of pipe at'the lower half of the pipe line. As is clearly apparent the-inner surface of the female portions and the The interior of the pipe secouter faces of the flanges are slightly tapered. This tapering makes the oining of pipes more easy to accomplish and additionally insures a better connection. l Vhen two sections of pipe are being attached together mortar 23 is used.
It will be seen that the Lshaped grooves 18 in the female portions of one pipe section interlock with similar grooves in the female portions of the adjacent pipe section of which connection is being made and that the mortar 23 is also placed in these grooves to insure water-tight and rigid connection.
Attention is directed to the fact that the pipe line automatically alines itself by reason of the engagement between the successive pipe section female portions and pipe section shoulders or flanges.
Additionally, the pipe when being laid will have no tendency to roll or fall over as it is supported on the large flat base 10. This base 10 is of a decided advantage and greatly simplifies the laying of the pipe line.
It will readily be apparent that the abutment portions 19 of the adjacent pipe sections abut one another with a layer of mortar in between. It will also be seen that the vitrified plate by protecting the pipe adds materially to its life.
The walls 17 at the rear ends of the flanges or collars 15 and 16 of the pipe sections are abutted b the outer end of the female portions of t e next adjacent pipe section when the sections are joined to form a pipe line. A layer of mortar is also present between these abutting surfaces.
The pipe section appearing in Fig. 5 of the drawings is designated B and is similar in all respects to the pipe sections A, with the exception that the vitrified line plate 20 is not used, nor is the pipe provided with the base 10. Unless the pipe is to be used to carry liquid having an acid content it is not necessary to utilize the vitrified line plate.
v too greatly stressed. The advantage referred ,to is that the present joint greatly facilites It will be readily apparent that the shoulders 15 and 16 are inset a distance slightly greater than thethickness of the female por tions 13 and 1 1, and that the female portions 13 and 14 are made of a thickness so that when they receive the shoulders 15 and 16 of adjacent pipe sections, the combined thickness of the female portions and shoulder is slightly less than the thickness of the pipe. The dimensions mentioned above are necessary to provide a space for the mortar so that when the joint between the sections is com pleted the outer and inner surfaces of the pipe sections will be in aflush position.
One advantage of a pipe connection made in accordance with this invention cannot be and simplifies the laying of a pipeline. At
the present time there is pipe being made which has a collar completely encircling the 1,75s,eee
end of the pipe. W'ith a construction having such a collar it is necessary to move the pipe sections longitudinally and slide them into engagement. This longitudinal movement of the pipe is diihcult to accomplish. Additionally, it is difiicult to properly apply the mortar to securely fasten the pipes together. lVith the present construction, it will be seen, however, that by building a pipe line, starting with the right hand end of a pipe section, the section to be joined can be dropped or lowered vertically into proper engagement to complete the joint between the sections' Before the joint is made, the mortar can be easily placed on the end of the section of the pipe already laid and it only remains to lower an additional section in place. No longitudinal movement of the sections is necessary, as the interlocking connection between the sections having the female portions 13 and 14 and the collars 15 and 16 is such that it can be made when one section is lowered vertically into position upon another section. As a poured concrete pipe section, especially in the larger sizes, is very heavy the advantage of eliminating the longitudinal movement of the section can be well appreciated.
Having thus described our invention, what we claim and desire to secure by Letters Patent is A pipe joint comprising two pipe sections, each having half the edge margin at one end thereof provided with a male portion of an external diameter less than the external diameter of the body portion of the pipe section, said male portion providing an external shoulder at its junction with the body portion of said pipe section, the other half of the edge margin being cut away internally to provide a female portion and an internal shoulder at the inner end of said female portion, said male and female portions being adapted for overlapping engagement with the complementary portions of the adjoining end of the other pipe section.
In testimony whereof we hereunto atfix our signatures.
